A small stellar sized black hole would be on the order of at least 3 solar masses. It would mean that we were part of a binary system with a supernova or somehow the solar system captured a rogue black hole. I’m not an astrophysicist but I‘m not sure what the orbital dynamics of that scenario would entail. I’m assuming you’re actually referring to a primordial black hole, something formed during the Big Bang, which could theoretically have smaller masses?

Not “OCD” but mission time constraints based on his project. If you can’t help, instead of being flippant or dismissive, don’t comment.
